@c2blackz or anyone else that needs help, what worked for me was to
1) Launch GTA 5 from the Epic Games Launcher.
2) Wait for it to load into Story Mode.
3) Open your explorer and go into C:\Program Files\Epic Games\GTAV, which is the default installation for Epic Games.
4) Scroll down until I see RAGEPluginHook.exe.
5) Open RAGEPluginHook.exe and you might get the settings windows.
6) If you don't get the settings screen, then it will automatically hook into your current game.
7) If you do get the settings screen, click the "Save and Launch" Button and it will hook into your game
Hope this helps! 😃
